Double Walled Carbon Nanotubes | Image Resource : carbonallotropes.com Carbon nanotubes even known as CNTs are recognized as allotropes of carbon that are structured in a cylindrical manner. The diameter to length ratio of these tubes is about 132,000,000:1 and this is what makes it the powerhouse of unusual properties that are quite valuable for the field of nanotechnology, optics, electronics, material science and many more. In particular, these extraordinary tubes hold impressive electrical, mechanical and thermal properties.
These nanotubes are categorized into three types which are single walled nanotubes (SWNTs) and double walled nanotubes (DWNTs) and multi walled nanotubes (MWNTs). Just as the name suggests SWNT are those tubes that hold a single wall, double walled hold two layers and multi-walled have multiple layers of carbon nanotubes. But the question still remains to be the same are double walled carbon nanotubes really better than the single walled nanotubes? Know More about Double walled Carbon Nanotubes To understand which one is better, it’s important to have a look over their structural design along with properties that they pose. Single Walled Carbon Nanotubes (SWNTs) have a small diameter that is close to 1nm; however this can grow to a million times longer in accordance to the length of the tube. This means that the structure of these tubes can be extended by utilizing one-atom thick layer of graphene, which helps in having a seamless cylinder. There are significant properties projected by SWNTs. However, the effectiveness of their property varies with the pair of graphene indices that they hold. This is the reason why the band gap of these tubes can range from 0 to 2eV along with that the electrical conductivity fluctuates from semiconducting to metallic behaviour. This is something that makes these tubes best for miniature electronics, as the basic building block of this system is considered to be an electrical wire. On the other hand DWNTs are special class of nanotubes that strangely project similar properties to that of SWNTs. This is because the morphology of double walled carbon nanotubes is just the same. However, the resistance of DWNT’s to harsh chemicals is better when compared with SWNTs. This property turns out to be quite important especially when functionalization is needed, in order to add important properties to the CNT. This where the single walled structure of nanotubes would break and this might leave certain holes in them, destroying its electrical and mechanical properties. Final Verdict- Buy Double Walled Carbon Nanotubes or Single Walled When it comes to the purchase of single walled or double walled nanotubes, then the choice is completely dependent on the type of project that you are dealing with. Though there are a few differences between the two kinds, but there are certain studies that prove double walled carbon nanotubes can be a better option for nanomechnical devices. Hence, if you are looking for an efficient two wall carbon nanotube that holds impressive restive capabilities against harsh chemicals then DWCNTs can be the perfect pick for you. But, when you decide to purchase them do make sure to get it from a reliable manufacturer.
